Pl Sql Exception Get Error Message
Tried to open a cursor that was already open DUP_VAL_ON_INDEX ORA-00001 An attempt to insert or update a record in violation of a primary key or unique constraint INVALID_CURSOR ORA-01001 The In Example 11-3, a procedure uses a single exception handler to handle the predefined exception NO_DATA_FOUND, which can occur in either of two SELECT INTO statements. However, the code block below does not work (I am experiencing a "found / expecting" syntax error) CREATE OR REPLACE PROCEDURE DBP.TESTING_SP AS DECLARE v_code NUMBER; v_errm VARCHAR2(64); BEGIN UPDATE PS_NE_PHONE_TBL Below that, the unnamed block itself has 'sub' savepoints - one foreach insert/update/delete statement in it, and one for each subprogram unit. this content
Target and Error tables have all fields that are present in source tables. VALUE_ERROR An arithmetic, conversion, truncation, or size-constraint error occurs. CASE_NOT_FOUND ORA-06592 -6592 None of the choices in the WHEN clauses of a CASE statement were selected and there is no ELSE clause. CURSOR_ALREADY_OPENED ORA-06511 -6511 Program attempted to open an already opened cursor.
But when the handler completes, the block is terminated.

Example 11-16 Exception Raised in Declaration is Handled by Enclosing Block BEGIN DECLARE credit_limit CONSTANT NUMBER(3) := 5000; BEGIN NULL; END; EXCEPTION WHEN VALUE_ERROR THEN DBMS_OUTPUT.PUT_LINE('Exception raised in declaration.'); END; / Example 11-1 Setting Value of PLSQL_WARNINGS Compilation Parameter For the session, enable all warnings—highly recommended during development: ALTER SESSION SET PLSQL_WARNINGS='ENABLE:ALL'; For the session, enable PERFORMANCE warnings: ALTER SESSION SET PLSQL_WARNINGS='ENABLE:PERFORMANCE'; The invoker does not handle the exception, so PL/SQL returns an unhandled exception error to the host environment. If no exception has been raised, SQLCODE returns zero and SQLERRM returns the message: ORA-0000: normal, successful completion.
WHEN OTHERS THEN -- optional handler sequence_of_statements3 END; To catch raised exceptions, you write exception handlers. This will be after the first occurrence of 'name' and the newline. */ v_Index := INSTR(v_CallStack, 'name') + 5; /* Loop through the string, finding each newline. This package stores general error information in the errors table, with detailed call stack and error stack information in the call_stacks and error_stacks tables, respectively. anchor For more information on error-handling and exceptions in PL/SQL, see "PL/SQL Error Handling" in Oracle Database PL/SQL Language Reference.
Note: Unreachable code could represent a mistake or be intentionally hidden by a debug flag. The exception handler cannot transfer control back to its own block.

Although you cannot anticipate all possible errors, you can plan to handle certain kinds of errors meaningful to your PL/SQL program. http://stackoverflow.com/questions/12327643/how-to-catch-and-return-or-print-an-exception-in-an-oracle-pl-sql-create-or-re So, the sub-block cannot reference the global exception unless it was declared in a labeled block, in which case the following syntax is valid: block_label.exception_name The following example illustrates the scope These are known as user-defined exceptions. Use of TimesTen expressions at runtime TimesTen SQL includes several constructs that are not present in Oracle Database SQL.
Note: When using pragma RESTRICT_REFERENCES to assert the purity of a stored function, you cannot specify the constraints WNPS and RNPS if the function calls SQLCODE or SQLERRM. http://iipseconline.com/pl-sql/pl-sql-error-exception-handling.html User-defined exceptions are exceptions specific to your application. This avoids compilation errors. User-defined You can declare your own exceptions in the declarative part of any PL/SQL anonymous block, subprogram, or package.
However, you can use SQLERRM to check whether a particular number is a valid Oracle error or to return the error message corresponding to a particular error code. If we try to delete a product_id from the product table when it has child records in order_id table an exception will be thrown with oracle code number -2292. Error-handling code is scattered throughout the program. http://iipseconline.com/pl-sql/pl-sql-exception-print-error-message.html Continuing after an Exception Is Raised An exception handler lets you recover from an otherwise fatal error before exiting a block.
Example 11-4 Locator Variables for Statements that Share Exception Handler CREATE OR REPLACE PROCEDURE loc_var AUTHID DEFINER IS stmt_no POSITIVE; name_ VARCHAR2(100); BEGIN stmt_no := 1; SELECT table_name INTO name_ FROM EXCEPTION WHEN OTHERS THEN -- cannot catch the exception ... The error number and message can be trapped like any Oracle error.
You must raise a user-defined exception explicitly.
If the transaction fails, control transfers to the exception handler, where you roll back to the savepoint undoing any changes, then try to fix the problem. Before starting the transaction, mark a savepoint. Use the RAISE statement by itself within an exception handler to raise the same exception again and propagate it back to the calling environment. Each handler consists of a WHEN clause, which specifies an exception, followed by a sequence of statements to be executed when that exception is raised.
ORA-01476 For Example: Suppose a NO_DATA_FOUND exception is raised in a proc, we can write a code to handle the exception as given below. share|improve this answer answered Sep 8 '12 at 3:01 DCookie 28.9k84765 awesome, thanks! In Figure 11-1, one block is nested inside another. check my blog That way, you can report errors to your application and avoid returning unhandled exceptions.
Exception Name Reason Error Number CURSOR_ALREADY_OPEN When you open a cursor that is already open.
